It has become. Reference numeral 3 denotes a fixed portion which forms a fixed portion of the joystick 10, and a plurality of fixed contacts Smn (m = 1, 2: corresponding to the operation amount) selectively contacting the movable contact C according to the operation content of the operation shaft 1. n = 1 to 8: corresponding to the operation direction). For example, the fixed contact S1n comes into contact with the movable contact C when the inclination of the operation shaft 1 is smaller than a predetermined angle, and the fixed contact S2n comes into contact with the movable contact C when the inclination of the operation shaft 1 is larger than a predetermined angle. Thus, for example, the fixed contact Sm1 is in contact with the movable contact C when the tilt direction of the operation shaft 1 is up, and the fixed contact Sm5 is in contact with the movable contact C when the tilt direction of the operation shaft 1 is down. It has become. That is, the fixed contact Smn indicates the number of the fixed contact that contacts the movable contact C according to the inclination angle of the operation shaft 1, and n indicates the fixed contact that contacts the movable contact C according to the operation direction of the operation shaft 1.

Next, the scroll operation will be briefly described. When the operator operates the joystick 10, the image is moved in the operation direction (direction in which the operation shaft 1 is inclined). If the tilt angle of the operation shaft 1 is small (the fixed terminal S1n is grounded), the image is continuously moved until the operation of the operation shaft 1 is released. If the tilt angle of the operation shaft 1 is large (the fixed terminal S2n is grounded), even if the operation of the operation shaft 1 is released, the image continues to move. For example, the image can be moved in the other direction or the joystick 10 can be moved. The movement of the image is continued until an operation other than the operation is performed.

Next, the scroll operation will be briefly described. When the operator operates the joystick 20, the image is moved in the operation direction (the direction in which the operation shaft 21 is inclined) while the operation is being performed. Further, when the joystick 20 is operated and the pressing switch 24 is pressed, even if the operation of the operation shaft 21 is released, the movement of the image is continued. The movement of the image is continued until an operation other than the operation of the joystick 20 is performed.
[0012]
Next, a third embodiment of the operation unit will be described. FIG. 3 is a configuration diagram showing a joystick of the third embodiment of the operation unit. The contact structure for detecting the operation direction of the joystick is substantially the same as the configuration of the joystick shown in FIG. An operation shaft 31 of the joystick 30 is a portion operated by an operator, and is configured to return to a neutral position when not operated by a spring or the like.
[0013]
P <b> 1 to P <b> 8 are direction indication switches configured by pressing switches provided in eight directions around the operation shaft 31.
Next, the scroll operation will be briefly described. When the operator operates the joystick 30, the image is moved in the operation direction (direction in which the operation shaft 21 is inclined) while the operation is being performed. When the operator operates the direction indicating switches P1 to P8, the image is moved in the direction corresponding to the operated direction indicating switches P1 to P8. The movement of the image by the direction instruction switches P1 to P8 is continued even when the operation is released. For example, the image is moved until an operation for moving the image in another direction or an operation other than the operation of the joystick 20 is performed. Movement continues.
[0014]
Next, the configuration of an electronic map display system that displays a map on a display based on map data recorded on an optical disk or the like will be described with reference to FIG. FIG. 4 is a configuration diagram showing the configuration of the electronic map display system. Reference numeral 41 denotes a direction instruction operation unit for performing a scroll operation, and for example, the joystick shown in FIGS. 1, 2, and 3 is used.

[0015]
Next, processing performed by the microcomputer 43 will be described. First, parameters used in the processing and a relationship between the parameters and the image will be described. FIG. 5 is an explanatory diagram of parameters used for processing of the microcomputer 43. X and Y indicate the horizontal movement speed and the vertical movement speed (distance that the image moves in one process), respectively, 0 in the stop state, 1 in the normal speed, and 2 in the high speed. That is, at a high speed, the moving speed (scroll speed) is twice the normal speed. Accordingly, the moving state (direction, speed) of the image is indicated by coordinates (X, Y) (X = −2, −1, 0, 1, 2: Y = −2, −1, 0, 1, 2). 16 types (excluding the origin). The flag A indicates whether to select a normal scroll that stops scrolling when the operation of the operation unit 41 is canceled or a continuous scroll that does not stop scrolling even when the operation of the operation unit 41 is canceled. Continuous scrolling, 0 indicates normal scrolling.
Next, processing performed by the microcomputer 43 will be described. FIG. 6 is a flowchart showing processing performed by the microcomputer 43, and is repeatedly executed while the electronic map display system is in operation.
[0016]
In step S1, it is determined whether an operation for moving (scrolling) the map, that is, whether the operation unit 41 is operated. If there is an operation, the process proceeds to step S2, and if there is no operation, the process proceeds to step S7. In step S2, the direction indicated by the signal from the operation unit 41 is detected to set the direction of scrolling the map, and the process proceeds to step S3. That is, as shown in FIG. 5, the X-direction speed and the Y-direction speed are set to −1, 0, 1 according to the indicated direction. In step S3, it is determined whether a continuous scroll operation is instructed. If continuous scroll is instructed, the process proceeds to step S4, and if there is no continuous scroll instruction, the process proceeds to step S6. This determination differs depending on the type of the operation unit 41, but in the case of FIG. 1, it is determined by the grounded fixed contact, in the case of FIG. 2, the state of the push switch 24, and in the case of FIG. it can.
[0017]
In step S4, the flag A is set to the continuous scroll state (1), and the process proceeds to step S5. In step S5, in order to set the scroll speed to twice the normal speed, the parameters X and Y are each doubled and the process proceeds to step S6. In step S6, the map displayed on the screen is moved X in the x direction (right direction) and Y is moved in the y direction (upward direction). For example, the movement unit may be set to 1 pixel or 2 pixels, and the image may be moved by multiplying the movement unit by X and Y. In step S7, it is determined from the flag A whether or not a continuous scroll instruction is issued. If continuous scroll is instructed, the process proceeds to step S8. If no continuous scroll instruction is issued, the process ends. In step S8, it is determined whether or not there is another operation (an instruction operation in another direction or an operation not related to the direction instruction). If there is another operation, the process proceeds to step S9, and if not, the process proceeds to step S6. In step S9, the continuous scroll is canceled (flag A = 0), and the process ends.
[0018]
Next, a fourth embodiment of the present invention will be described. FIG. 7 is a diagram showing the basic configuration of the fourth embodiment of the present invention. In the present embodiment, the operation unit 41 is a joystick that outputs a voltage corresponding to the operation amount of the operation axis (for each of the horizontal direction (x direction) and the vertical direction (y direction)). This type of joystick has an operation shaft 73 fixed by an x-axis swing arm that can rotate about an x-direction axis and a y-axis swing arm that can rotate about an y-direction axis. It is composed of variable resistors VR1 and VR2 connected to the respective axes of the arm and the y-axis swing arm, and a voltage corresponding to each operation amount of the operation shaft 73 in the x direction and the y direction (power supply by the variable resistors VR1 and VR2 of the power supply voltage). The voltage Vcc is divided and output).
[0019]
The output voltages V1 and V2 from the variable resistors VR1 and VR2 are V2 is the maximum value (V2max = Vcc) at the upper end operation position of the operation shaft 73, V2 is the minimum value (V2min = 0) at the lower end operation position, and the right end V1 is the maximum value (V1max = Vcc) at the operating position, V1 is the minimum value (V1min = 0) at the leftmost operating position, and the output voltages V1, V2 are intermediate values (V1cen = 1 / 2V1max, V2cen = 1 / V) at the neutral position. 2V2max). That is, the output voltages V1 and V2 have values as shown in FIG. 8 at the end portions in the eight directions and the neutral position (non-operation state), and according to the operation amount from the intermediate position between the end portions and the neutral position. The intermediate value will be taken.
[0020]
Next, the relationship between the output voltages V1 and V2 and the moving speed of the image (image moving amount in one process) will be described. Since the moving speed is 0 at the neutral position, first, the difference between the output voltages V1 and V2 and the voltages 1 / 2V1max and 1 / 2V2max at the neutral position is taken. Next, in order to take the actual operation ratio with respect to the maximum operation amount, the obtained difference is divided by the voltages V1max and V2max at the maximum operation position. This value is a ratio of the image moving speed to the operation amount of the operation shaft 73. Furthermore, in order to set the maximum moving speed at the time of the maximum operation as a desired speed, the calculated ratio is multiplied by twice the desired maximum moving speed (value with respect to the unit speed) to obtain the moving speed of the image. That is, it may be calculated by the following formulas 1 and 2.
a = (V1−1 / 2V1max) / V1max × 2 · Maximum moving speed Equation 1
b = (V1−1 / 2V2max) / V2max × 2 · Maximum moving speed Equation 2
Next, the scroll operation will be briefly described. When the operator operates the operation shaft 73 of the joystick, the operation direction (direction in which the operation shaft 73 is inclined) and the operation amount (inclination angle) of the operation shaft 73 are performed while the operation is being performed. Move the image at speed. If the tilt angle of the operation shaft 73 is large (exceeds 2/3 of the maximum operation amount), the image is moved even if the operation of the operation shaft 73 is released, and the movement is continued at the speed at that time. For example, the movement of the image is continued until an operation other than the operation of moving the image in the other direction or the operation of the operation shaft 73 of the joystick is performed. In the following process, when the operation shaft 73 is operated again to 2/3 or less of the maximum operation amount, the continuous scroll is released, but the continuous scroll is not released during the continuous scroll (A = 1). In addition, it is possible to prohibit the release of the continuous scroll by the process of reducing the maximum operation amount by the operation shaft 73 during the continuous scroll.
[0021]
Next, processing performed by the microcomputer 43 in the fourth embodiment of the present invention will be described with reference to a flowchart. FIG. 9 is a flowchart showing the processing performed by the microcomputer 43, and this processing is repeated during the operation of the electronic map display system. In step S81, it is determined whether an operation for scrolling the map is performed. If there is an operation, the process proceeds to step S82, and if there is no operation, the process proceeds to step S85. In step S82, output voltages V1 and V2 from the joystick are detected, the image moving speeds a and b are calculated according to the above-described equations 1 and 2, and the process proceeds to step S83. Here, the maximum moving speed is set to 3. In step S83, it is determined whether the image moving speed a or b is greater than 2. If either of the image moving speeds a and b is large, the process proceeds to step S84, and if both are small, the process proceeds to step S87. In step S84, the flag A is set to 1 to continue scrolling, and the process proceeds to step S85. In step S87, the flag A is set to 0 for normal scrolling, and the process proceeds to step S85. In step S85, the movement amount of the image for one image display process is set to a and b (X = a, Y = b) in the horizontal direction and the vertical direction, respectively, and the process proceeds to step S86. In step S86, the image is moved X in the horizontal direction and Y in the vertical direction, and the process ends. In step S87, it is determined whether or not it is continuous scrolling based on the flag A. If it is continuous scrolling (A = 1), the process proceeds to step S88, and if it is not continuous scrolling, the process ends. In step S88, it is determined whether or not there is a scroll operation in another direction or an operation other than scrolling. If there is, the process proceeds to step S89, and if there is not, the process proceeds to step S86. In step S89, the continuous scroll is released (A = 0) and the process is terminated.
